i recently installed a new fuel pump and filter. Ever since i installed these parts whenever the customer tries to put gas in it, the fuel backs out the top of fill neck. I have check fill tube and vent tube for restrictions, there was none. Any suggestion would be greatly appreciated.

Has to be a vent issue somewere.

The rollover protection valve and fuel vent valve are built into the fuel pump module on this I believe. It's likely you have a defective unit. I'd pull the pump and check.

Thanks for the input. I was thinking pump also. Will post what happens. Once again thanks
